kwin/tabbox/qml/IconTabBox.qml
Weng Xuetian 5b7a30aeac use qml and svg to drag shadow in tabbox
due to plasma change, shadow is not included by default, hence kwin
tabbox need to handle shadow by itself, and due to kwin is compositor
and have shadow as effects, it's not a good idea to use X property to
pass shadow from kwin to X and to kwin. This change use the old way to
draw shadow side the tabbox, and partly move the blur region setting to
qml.
